Abstract

A capacitively coupled printed patch (3) as a high efficiency device to couple orthogonally polarised energy between a stripline (5) and a waveguide (1). Coupling between the stripline (5) and the patch (3) is achieved by the stripline terminating in a narrow strip probe (4), the end of which lies close to, but not in contact with, an edge of the patch (3). Two separate probes (4) arranged mutually orthogonally are used to effect independent polarised couplings to produce independent linear orthogonal signals or independent left- and right-handed circularly polarised signals. The striplines (5) and patch (3) are supported on a common substrate (8) which extends transversely through the waveguide (1). The waveguide wall has a quarter-wavelength thickness (T) so that its inner edge (10) appears continuous to energy passing through the substrate (8). One application is in a DBS satellite TV receiving system where it is required to isolate two signals sharing a common channel but having orthogonal polarisations.
